A Wood charcoal is a soft, black, porous solid.
C It adsorbs colouring matter.
D It adsorbs gases.
Wood charcoal is a soft, black and porous solid which is brittle and tasteless. It is a bad conductor of heat and electricity.
It is a good adsorbent of gases as this can be understood by taking a jar filled with hydrogen sulphide which smells like rotten eggs and after putting wooden charcoal we will close the lid. We will shake the jar for a few minutes and after removing the lid of jar we will notice that there is no smell in the jar. This proves that wooden charcoal is a good adsorbent for gases.
Wood charcoal even adsorbs colouring matter from solution and this can be understood by putting some drops of ink in the glass of water. Water turns blue due to ink drops but after the small quantity of wood charcoal powder, we will observe the colour of the solution fades away.
